Description

The invention relates to a system for realizing a lamp and a method for realizing a lamp and a lamp.

Generic lights or generic systems for implementing generic lights are well known in the prior art and are used in particular for illuminating large rooms, such as sales rooms or factories. For this purpose, the lights are preferably elongated, so that light strips can be implemented in a simple manner, and have a modular structure. In principle, however, the invention is also applicable to non-elongated lights. The basic components of such a lamp are at least a mounting rail and a cover. The mounting rail is designed to be fixed to a component, such as a ceiling or a wall. The cover is designed to form a termination of the lamp, through which the lamp can emit light. The mounting rail and cover are also preferably elongated. Often, a plurality of mounting rails and a plurality of covers are used to implement an elongated luminaire, which are then arranged next to one another in the longitudinal direction to implement an elongated luminaire designed as a light band. Often include generic Also illuminate a device carrier, which is fixed to the mounting rail, in particular is arranged in a space delimited by mounting rail and cover. Basic components of the luminaire, such as lamps, which in particular comprise a circuit board with LEDs, electronic ballasts and the like, such as connectors and cables, are then arranged on the device carrier. In sections in which the lamp has no lamps on the device carrier, the device carrier can be designed as a dummy module. In the case of generic lamps to which the invention relates, the carrier rail, cover and device carrier are preferably elongated.

It is desirable for generic luminaires that they can be used in a variety of different settings. In particular, efforts are being made to design such luminaires in such a way that they are dustproof and in particular watertight, for example in accordance with the IP 54 standard. Various approaches are known in the prior art to ensure such a seal. On the one hand, it is known to provide seals between the various components of a lamp, which seal these components against one another. For example, it is known to insert a circumferential seal between the cover and the mounting rail. It is also known, on the one hand, to seal the device carrier from the mounting rail by means of a circumferential seal, and, on the other hand, to seal the cover relative to the device carrier. Due to the elongated design of generic lights, this is associated with a not inconsiderable risk of causing leaks by moving the seal. It should be taken into account here that generic luminaires typically have a longitudinal extension that is at least five times, in particular at least ten times their extension in a direction perpendicular to Transverse direction and / or in a vertical direction perpendicular to the longitudinal direction. In addition, such a seal is cost-intensive and complicates the manufacture of the lamp, which at least slows down the manufacture of the lamp. There is also the approach of designing the mounting rail with a complex receptacle, in which the cover then engages in order to create a sealed space in which components of the luminaire and in particular the device mount are located. However, the realization of such a mounting rail with a complex receptacle and thus with a complex cross-section is complex and cost-intensive and can only be achieved with selected materials, such as an extruded aluminum profile, which is associated with considerable manufacturing costs.

The present invention is based on the object of providing a system for realizing a luminaire which at least partially eliminates at least one of the problems described in the generic system and in particular enables a luminaire which is sealed as easily and inexpensively as possible.

As a solution to the described problem underlying the invention, the invention proposes a system with the features of claim 1. The system according to claim 1 comprises at least one support rail, preferably elongated in the longitudinal direction, at least one cover, preferably elongated in the longitudinal direction, and at least one device carrier, preferably elongated in the longitudinal direction. An elongated design means that the extension of the respective element in the longitudinal direction is at least twice, in particular at least three times, in particular at least five times, in particular at least ten times that Extent of the element in the vertical direction and / or in a transverse direction that is perpendicular to the vertical direction and perpendicular to the longitudinal direction. The vertical direction is perpendicular to the longitudinal direction. The mounting rail has two side walls running along the vertical direction, which are connected to one another by a bottom section of the mounting rail running along the transverse direction. At least one of the side walls of the mounting rail has a receptacle, and the device carrier has at least one holding web. The receptacle is designed for the holding web, and in an operating position of the system, in which an elongated light is realized by the elements of the system, which are usually formed separately from one another, the holding web of the device carrier is arranged in the receptacle and the device carrier is fixed and vertical on the mounting rail held at a distance from the base section to form a receiving space, which is preferably between the base section, side walls and equipment carrier. The receptacle formed by the side wall is vertically open on the side facing away from the base section, so that the holding web can be inserted into the receptacle for fixing the device carrier to the mounting rail. Known forms of fastening can be set up to fix the retaining web in the receptacle, such as, for example, a form-fitting connection between the retaining web and side wall, in particular by means of a snap-in connection or another rear grip, or a non-positive connection. Of course, each of the side walls can each have a receptacle and the device carrier can have two holding webs, with one holding web being assigned to exactly one of the receptacles and the receptacle being designed to receive the holding web assigned to it, so that the device carrier has the respective receptacle and the respective assigned one Holding bridge is fixed on both side walls of the mounting rail. However, it is Of course, it is also possible that only one of the side walls has a receptacle and the device carrier has only one retaining web, the device carrier being held on the other side wall, which has no receptacle, by other means, for example by means of external fixing means or a clamp connection or the like. In the following, a receptacle and an associated holding bridge are always dealt with. If two receptacles are provided, that is to say in an embodiment in which each of the side walls forms a receptacle and the device carrier has two holding webs, one of which is assigned to exactly one of the two receptacles, the following explanations apply to both receptacles or both Retaining bars applicable. The cover has at least one fixing section with which it is held in the operating position on the mounting rail. The receptacle, the holding web and the fixing section are designed to correspond to one another in such a way that in the operating position the holding web and the receptacle together form a groove, a first groove wall of the groove being formed by the holding web and a second groove wall of the groove being formed by the side wall forming the receptacle and, in the operating position, the fixing section of the cover is arranged and held in the groove and in particular abuts the first groove wall and the second groove wall. The groove thus lies within the receptacle of the side wall and is formed by the holding web arranged at least in sections in the receptacle and a side wall section. Analogous to the above explanations regarding embodiments, in which each of the side walls each has a receptacle and the device carrier has two holding webs, each of which is assigned to exactly one of the receptacles, the cover can also have two fixing sections, one receptacle each associated with it Retaining web and the associated fixing section to each other as explained above are trained accordingly. Analogously, the following explanations regarding a receptacle, the holding web assigned to it and the fixing section assigned to it are applicable to embodiments in which each of the side walls each has a receptacle and accordingly two holding webs and two fixing sections are provided and in each case a receptacle, the holding web assigned to it and the fixing section assigned to it interact as explained above and explained below in further exemplary embodiments. Basically, the mounting rail preferably has a cross section perpendicular to the longitudinal direction, which is open along the vertical direction at a vertical end and is delimited along the transverse direction by the side walls, device carriers and cover being arranged at the open end of the cross section and at least the cover being open Closes end of the cross section. The receptacle, the holding web and / or the fixing section preferably extend over at least 50%, in particular at least 80%, in particular at least 90% of the longitudinal extension length of the mounting rail. The cover, retaining web and / or mounting rail preferably have a constant cross section over at least 50%, in particular over at least 70%, in particular at least 90% of their extension length.

The solution of the above-mentioned object on which the invention is based by a system according to claim 1 has significant advantages. Because by forming a groove for the cover with the aid of the device carrier and the mounting rail, a groove can be realized in a simple manner that has a cross section that is suitable for sealingly arranging the fixing section of the cover. It is therefore not necessary to form a groove with such a complex cross-section in the mounting rail itself, but the mounting in the mounting rail is targeted Corresponding to the holding web of the device carrier and the fixing section of the cover, so that the mounting rail, the holding web of the device carrier and the fixing section of the cover can contribute to the fixing of the holding web, cover and mounting rail to one another and thereby to the sealing of the elements to one another, thereby creating an outward connection sealed receiving space of the lamp can be provided, in which components of the lamp, such as lamps, are kept protected. For example, the mounting rail can be implemented in a simple manner and with simple means. The mounting rail is particularly preferably made from a sheet metal, in particular by forming a sheet metal. The device carrier is particularly preferably produced from a sheet metal, in particular by forming a sheet metal. According to an advantageous embodiment, the device carrier is made of plastic, in particular by means of extrusion processes and / or injection molding processes. The device carrier is particularly preferably suitable for receiving a lamp, in particular an LED lamp. The device carrier is preferably designed as a dummy module, it being possible for electrical functional elements such as, for example, a radio module to be provided on the dummy module. In certain embodiments, the dummy module has no electrical function module and in particular serves exclusively to cover the receiving space optically. The cover is particularly preferably made of a plastic, in particular by means of injection molding and / or extrusion processes. The cover particularly preferably comprises a cover main piece which forms at least 70%, in particular at least 80%, in particular at least 95% of the longitudinal extent of the cover and which forms the fixing section, the cover main piece being produced by means of an extrusion process. The cover can also be a cover end piece, for example have, which forms a longitudinal end of the cover and is connected to the cover main piece, in particular is sealingly connected. The cover can have, for example, two cover end pieces, each of which is arranged on one of the longitudinal ends of the cover main piece, so that the two cover end pieces form the longitudinal ends of the cover. The cover can be produced in a particularly cost-effective manner by implementing the cover or at least an essential longitudinal extension section of the cover by means of extrusion processes.

The fixing section particularly preferably presses along the transverse direction in one direction against the first groove wall and in the opposite direction against the second groove wall. This can support both fixing the cover with respect to the device carrier and mounting rail and fixing the device carrier with respect to the mounting rail. The fixing section particularly preferably presses with such a surface and force against at least one of the groove walls, in particular against at least the second groove wall, that the cover is sealed via the fixing section with respect to the mounting rail within the groove, preferably in accordance with IP 54, in particular in accordance with IP 64, in particular according to IP 65. Particularly preferably, the fixing section runs continuously along the longitudinal direction over at least 80%, in particular at least 95% of the longitudinal extension length of the cover, particularly preferably over the entire extension length along the longitudinal direction of the cover main piece, which is a one-piece component. Particularly preferably, the fixing section lies in the groove in a sealing manner over at least one of the groove walls, preferably at least on the second groove wall, which is formed by the support rail, over its entire longitudinal extension length.

In one embodiment, the first groove wall is arranged between the transverse center of the mounting rail and a transverse end of the mounting rail and the second groove wall is arranged in the transverse direction between the transverse end and the first groove wall. In this embodiment, the device carrier is thus offset inwards in the mounting rail, while the fixing section and thus a section of the cover extends in the transverse direction between the device carrier and the side wall and thus between the device carrier and the outer transverse ends of the mounting rail. This can ensure a particularly robust fixation of the cover on the mounting rail. In further embodiments, the device carrier encompasses the mounting rail. In general, additional, separate fixing means, for example known retaining springs, are preferably provided for fixing the device carrier to the mounting rail, so that the device carrier and the not inconsiderably heavy lamp components attached to it are reliably held on the mounting rail. The cover is preferably held on the mounting rail exclusively via its at least one fixing section.

In general, the mounting rail is particularly preferably made of sheet metal, particularly preferably by forming. The device carrier is particularly advantageously made of sheet metal, particularly preferably by forming. The device carrier can preferably be made of plastic, in particular by means of extrusion or injection molding. In general, the cover is particularly preferably made of plastic. The cover particularly preferably has a constant cross section over its entire extension length, in which it has the first fixing section. The side walls of the mounting rail particularly preferably form the receptacle by extending vertically downwards starting from the base section and then initially upwards and towards the transverse center then bent down again. As a result, a sufficiently stable receptacle can be realized in the side wall if the mounting rail is made from a sheet metal.

Particularly preferably, at least one of the groove walls, in particular both groove walls, form a step, the fixing section engaging behind the step, forming a positive connection acting along the vertical in the operating position. The fixing section is particularly preferably in contact with at least one of the groove walls with a contact pressure acting in the transverse direction. The fixing section particularly preferably engages behind a step provided on one of the two groove walls and bears against the other of the two groove walls with a contact pressure acting in the transverse direction. The cover can be held particularly well in the groove by a combination of engaging behind a step provided in one of the two groove walls and exerting a contact pressure in the transverse direction. Particularly preferably, at least the second groove wall forms the step explained, so that the cover is held directly on the mounting rail.

In one embodiment, the fixing section has two fixing arms which are spaced apart transversely from one another at least over a vertical section of the groove. In general, the fixing section preferably has a constant cross section over its entire longitudinal extent, so that the two fixing arms are transversely spaced apart from one another over the entire longitudinal extent of the fixing section. The fixing arms are particularly preferably transversely spaced apart from one another in a vertical section, which forms the vertical end section of the fixing section facing the bottom section of the mounting rail. A first of the fixing arms preferably lies on the first groove wall and a second of the fixing arms on the second groove wall. Particularly preferably, the two fixing arms can be deflected relative to one another in the vertical section, starting from a rest position in the transverse direction, with the formation of a restoring force acting in the transverse direction, wherein they form the restoring force in particular in the operating position. The two fixing arms are thus designed such that the fixing section in the vertical section mentioned can be elastically compressed along the transverse direction. In one embodiment, the fixing arms are connected to each other both at their vertically lower end and at their vertically upper end, but are spaced apart from one another in the vertical section which is located between their two vertical ends. This can also ensure such compressibility of the fixing section in the vertical section in the transverse direction. Particularly preferably, at least one of the fixing arms, in particular at least the second fixing arm, is designed to be continuous over at least 90% of the length of the cover, in particular continuously with the same cross section. Particularly preferably, the cross section of the cover extends continuously and in one piece transversely to the opposite side wall of the mounting rail from a contact surface of the second fixing arm on a first of the side walls of the mounting rail. In one embodiment, the fixing section is formed in several parts. For example, the first fixing arm can comprise at least one, in particular a plurality of spring clips, which are each connected to the second fixing arm via a longitudinal section of the second fixing arm and press the second fixing arm against the second groove wall, the spring clips being produced independently of the second fixing arm. The second fixing arm is particularly preferably integrated in one piece in the main cover piece, particularly preferably the first and second fixing arm are integrated in one piece in the main cover piece.

The provision of two such fixing arms can have the particular advantage that the cover can be easily inserted into the groove with the fixing section and can be fixed therein. Particularly preferably, one of the fixing arms forms a projection which, in the operating position, bears vertically on the step which is formed by one of the groove walls. Particularly preferably, both fixing arms each form a projection, the projection of the respective fixing arm resting in the operating position on the step of the respective wall against which the respective fixing arm lies.

In general, the cover preferably lies in the operating position over a longitudinal section that is at least 80%, in particular at least 95% of the longitudinal extension length of the mounting rail, and is sealed in a dustproof and in particular watertight manner on the mounting rail, preferably according to the IP 54 standard, particularly preferably according to the IP standard 64, particularly preferably according to the IP 65 standard. The mounting rail and cover can thereby form an externally sealed receiving space in which, for example, the electrical components of the luminaire can be arranged.

In one embodiment, the holding web rests on the fixing section in the operating position in a direction running along the transverse direction and on a section of the receptacle in the opposite direction along the transverse direction, the section of the seating lying on the other transverse side of the holding web than the second Groove wall. The section of the receptacle can thus form a counterpart for the holding web, against which the holding web presses when the fixing section is arranged in the groove and presses against the first groove wall formed by the holding web. The holding web and the section of the receptacle particularly preferably engage behind one another in such a way that the holding web vertical form fit with the portion of the receptacle, for example via a latch or a tongue and groove connection. In general, the holding web is preferably locked in the receptacle on the mounting rail in the operating position, preferably with a vertical positive fit. In general, the holding web is preferably locked in the operating position on the section of the receptacle. The holding web can have, for example, two holding web sections spaced apart from one another in the transverse direction but running in the same vertical section. Such holding bar sections can be realized, for example, by reshaping a metal sheet if the device carrier is made from a metal sheet. For example, a first of the holding web sections can form the groove wall and a second, as explained, can rest on the section of the receptacle. This holding web section resting on the section of the receptacle can, for example, have a profile, by means of which it is held on the section of the receptacle with a vertical form fit, or via which it is held on the named section of the receptacle by means of a force fit.

In general, the fixing section preferably lies against the first groove wall and / or the second groove wall in a sealing manner over at least 90% of the longitudinal extension length of the mounting rail. In general, the fixing section is particularly preferably in a correspondingly sealing manner at least on the second groove wall. In general, a seal is particularly preferably provided on the fixing section, which extends over at least 90% of the length of the cover and in particular over at least 90% of the length of the mounting rail, with the seal resting on the first and / or second groove wall, preferably at least on the second groove wall to seal the cover against the mounting rail. The seal is particularly preferably made of a different plastic than that of it adjacent section of the cover, particularly preferably the material from which the seal is made is softer than the material of the cover area on which the seal is provided. For example, the cover can be made at least partially from an extrusion process. For example, the cover main piece of the cover can be produced from plastic by means of extrusion processes. For example, the seal can be realized in that at least the part of the cover, in particular the cover main piece, in particular the entire cover, is produced by means of a coextrusion process, for example by manufacturing by means of injection molding the seal onto a previously produced plastic element or by means of a two-component injection molding process. In an embodiment of the fixing section comprising two fixing arms, it is particularly preferred that at least the second fixing arm runs continuously along the second groove wall formed by the mounting rail. Particularly preferably, at least the second fixing arm extends continuously over at least 90% of the length of the cover. The seal mentioned is particularly preferably provided on the second fixing arm, with which the fixing section presses against the second groove wall.

In general, the device carrier preferably has two retaining webs and each of the side walls has a receptacle, and the cover has two fixing sections. One of the receptacles is assigned to one of the holding webs and one of the fixing sections. In the operating position, each of the receptacles forms an associated groove together with the associated holding web, a first groove wall of the associated groove being formed by the associated holding web and a second groove wall of the associated groove being formed by the respective side wall forming the respective receptacle. In the operating position, the associated fixing section of the cover is in the arranged associated groove and abuts the first groove wall and the second groove wall of this assigned groove. By means of a corresponding design of the equipment carrier, mounting rail and cover, both the equipment carrier and the cover can be held on the mounting rail at two spaced-apart transverse sections, namely over the respective side wall of the mounting rail, thereby ensuring a particularly robust fixation of the equipment carrier and cover relative to the mounting rail is guaranteed and in particular a particularly good seal of at least the cover with respect to the mounting rail.

In one embodiment, the system comprises a connector, by means of which two support rails which are adjacent to one another in the longitudinal direction and which are preferably of identical design or at least both have the features explained here with the aid of various exemplary embodiments, can be mechanically connected to one another. For this purpose, each of the side walls preferably has a connector guide, which is provided on the outside in the transverse direction on the receptacle formed by the respective side wall. The connector guide is thus spaced further from the transverse center than the receptacle. The connector guide can be produced, for example, by reshaping a metal sheet if the mounting rail is made from a metal sheet. For example, the connector guide can be formed by bending a side wall upwards from its vertically lower end. A section of the side wall, which forms the second groove wall, preferably also forms a side wall of the connector guide. The connector is designed for insertion into the mounting rails at the front along the longitudinal direction. In an inserted position, the connector preferably extends in the transverse direction between the outer wall section of the respective side wall and a section of the respective side wall forming the second groove wall. This allows the connector to be a Ensure stiffening of the mounting rail at the level of the groove, as a result of which the cover and in particular also the equipment carrier can be held on the mounting rail in a particularly reliable manner. This is because the connector, when inserted into the connector guide, can stabilize the second groove wall, so that the cover and device carrier, when they are arranged with their fixing section or retaining web in the receptacle, counteract to the outside with a not inconsiderable force in the transverse direction be able to press the second groove wall without causing any noticeable deformation of the mounting rail. The connector is preferably U-shaped, the bottom section of the U-shape of the connector in the inserted position running along the bottom sections of the two adjacent mounting rails and the legs of the U-shape being arranged in the connector guides of the two adjacent mounting rails and thus between the second groove wall and a wall section of the side walls of the mounting rails forming the transverse outside of the mounting rail. In embodiments in which no connector is provided, for example, the side walls can inherently have sufficient stability. Furthermore, in embodiments, the sealing device explained below can help stabilize the side walls, so that the side walls can withstand a sufficient contact pressure of the fixing section.

In one embodiment, the system comprises a holding spring for holding the device carrier on the mounting rail. The holding spring can thus enable a reliable fixation of the device carrier on the mounting rail, in particular essentially guarantee such a fixation, whereas the arrangement of the holding web in the receptacle preferably serves for sealing. The retaining spring can be fixed in position on the equipment carrier. The retaining spring is designed to be in the operating position by the To engage behind the side walls of the mounting rail formed profile. The holding spring has at least one spring arm which engages behind the profile in the operating position and which can be deflected in the transverse direction from its position in the operating position to the transverse center of the mounting rail. The profile is preferably formed by the design of the receptacle through the side wall. A receptacle for an actuating element is provided on the spring arm. One of the side walls of the mounting rail and / or a side wall formed by the device carrier has an opening for the actuating element. In a state in which the holding spring fixes the device carrier to the mounting rail, the actuating element can be inserted and locked with it in the receptacle of the spring arm along the transverse direction from outside the mounting rail through the opening, while it is transversely across the mounting rail with an operating section on the outside protrudes to allow actuation of the spring arm to move the spring arm along the transverse direction. In one embodiment, the cover covers the opening in the operating position. Particularly preferably, starting from the operating position, the cover can be detached from the mounting rail and then the actuating element can be inserted from the outside in the transverse direction through the opening of the mounting rail into the receptacle of the spring arm and locked with it, while the device carrier is still held on the mounting rail by the retaining spring is. The actuating element is particularly preferably releasably lockable in the receptacle of the retaining spring. The described embodiment has the particular advantage that a sealed lamp can be realized, in which the retaining spring is not accessible from the outside, since the opening provided in the mounting rail is closed by the cover, the operating element not being on the retaining spring in the operating position is fixed and thus a small-sized lamp can be realized.

By inserting and latching the actuating element in the receptacle of the spring arm of the retaining spring after dismantling the cover, starting from the operating position, it is simultaneously possible to remove the device carrier from the mounting rail.

In one embodiment, the device carrier of the system is designed as a dummy module. A blind module means an embodiment of the device carrier which has no lamps, in particular no devices or provisions for receiving lamps. The blind module can be designed as a sheet metal component. The blind module is preferably produced from sheet metal by means of forming. The dummy module is particularly preferably made of plastic. In particular, the blind module is produced by means of extrusion and / or injection molding processes. The system particularly preferably has a first group of device carriers on which lamps are arranged, and a second group of device carriers which are designed as blind modules, in particular at least one, in particular all, of the device carriers of the second group having a lower weight than that Equipment carrier of the first group, and / or wherein in particular at least one, in particular all, of the equipment carrier of the first group is made of sheet metal and / or at least one, in particular all, of the equipment carrier of the second group is made of plastic. In advantageous embodiments, the dummy module can be produced, in particular by means of a multi-component method, comprising more than one type of plastic and / or metal components. Of course, various possibilities for stiffening the device carrier, in particular the dummy module, for example through the provision of metal-reinforced sections, are known to the person skilled in the art. In a preferred embodiment, the blind module is for receiving devices for operation, for energy supply and / or for controlling lights suitable. Such devices can be transmitting and / or receiving modules for control signals, sensors, signal and / or energy-carrying lines, in particular cables. The blind module particularly preferably has means for routing the line. The cable guides can be suitable for guiding cables for the transmission of electrical energy and / or material media. Of course, the dummy module can also be designed without additional devices and / or provisions for additional devices. The blind module is particularly preferably produced in one piece and thus a component which is integrally manufactured.

In one embodiment, the system is designed such that a first holding force for fixing the fixing section on the first groove wall is greater than a second holding force for fixing the holding web on the receptacle. The holding web on the receptacle can thus be held with a lower holding force than the holding section on the first groove wall. The holding force means a force whose amount must at least be reached in order to release a connection. To release the connection between the mounting rail and the device carrier in the operating position, a release force is required, the amount of which corresponds at least to the holding force. The holding force and the releasing force are in particular opposite. In the case of non-positive connections, the amount of the holding force can correspond to the amount of the normal force generating the frictional connection for generating a frictional force, in particular the amount of the frictional force. For connections, the loosening of which requires both the overcoming of the positive connection and the overcoming of the positive connection, the releasing force can be greater, in particular at least 20% greater than the frictional force required to carry out the releasing movement. The system can start from the operating position can be transferred to a maintenance position. In general, the maintenance position can denote any position in which the equipment carrier and cover, in particular only the equipment carrier, do not rest on the mounting rail. The system can be transferred from the operating position to the maintenance position by a release movement. In the maintenance position, the device carrier is detached from the mounting rail, the cover being held on the device carrier, in particular in the maintenance position, in particular by the interaction between the fixing section and the retaining web. Particularly preferably, the device carrier remains permanently fixed to the cover during the release movement, during which the system is transferred from the operating position to the maintenance position, in particular by the interaction of the holding web and the fixing section. The release movement is preferably carried out along a vertical direction. The release movement can be initiated in particular by overcoming the holding force by applying the release force. The fixing section is held in the operating position on the first and / or second groove wall. The holding web is held in the operating position on the receptacle. In the operating position, the holding force by which the fixing section is held on the first and / or second groove wall is preferably greater than the holding force by which the holding web is held on the receptacle. The release movement can be initiated, in particular by exceeding the lower holding force, and transfers the system from the operating position in which the holding web is held to the receptacle to the maintenance position in which the holding web is released from the receptacle and in particular the fixing section is held in the same position on the first groove wall as in the operating position. During the release movement, the device carrier is preferably arranged continuously in the same position relative to the cover. In particular, the relative position of the cover to the mounting rail and the Relative position of the device carrier to the mounting rail can be changed simultaneously by the release movement. Starting from the operating position, the system can preferably be transferred to a maintenance position by releasing the cover relative to the mounting rail, in which the device carrier is held on the cover by the interaction of its retaining web with the fixing section of the cover. In particular, the device carrier and the cover can be released from the mounting rail together, the device carrier in particular being continuously arranged in the same position relative to the cover during the release movement starting from the operating position. In particular, the device carrier and the cover are still in the same relative position to one another as in the operating position after the release movement. In particular, the device carrier and the cover can be released from the mounting rail together from the operating position by the releasing force acting exclusively on the cover. In preferred embodiments, all retaining webs can be detached from the fixing section at the same time or at least one after the other by applying a releasing force, in particular by the releasing force acting exclusively on the cover.

In an advantageous embodiment, the device carrier has at least one detent spring in the transverse direction between the holding web and the transverse center of the device carrier. In particular, the detent spring is integrally formed in the device carrier. The detent spring, in particular the entire device carrier, is preferably made of plastic. The detent spring is preferably arranged between the holding web and the transverse center of the device carrier. The latching spring preferably extends vertically, preferably vertically, in the direction of the bottom section of the mounting rail, preferably from a section of the device carrier that closes the open end of the mounting rail in the operating position. The extension of the detent spring thus has at least one vertical component, in particular the vertical extension predominating over the transverse extension. The detent spring rests against a section of the mounting rail in the operating position. In the operating position, the catch spring preferably lies on a section of the receptacle between the transverse center and the first groove wall on the side facing away from the groove. The detent spring can rest on a section of the side wall of the mounting rail. The retaining web and the detent spring can each be deflected, in particular with the formation of a restoring force. The retaining web and the detent spring can preferably be deflected in a transversely opposite direction, in particular such a deflection generating a restoring force. Starting from the operating position, the retaining web and the detent spring can each be elastically deflected in the transversely opposite direction by forming the restoring force. The restoring force is proportional to the deflection and can differ in size and course for each retaining web and for each detent spring. An elastic deflection is to be understood in such a way that the reduction in the restoring force has the result that the detent spring and / or the retaining web return to an initial position. The starting position is the position in which the detent spring or the retaining web each do not form a restoring force. In particular, the device carrier is held in the operating position by the holding web on the mounting rail. In particular, the device carrier is held in the operating position by the detent spring on the mounting rail. The device carrier is preferably held in the operating position by both the retaining web and the detent spring on the mounting rail. In the event of mechanical stress on the system which is possible in the operating state, in particular as a result of vibrations applied externally to the system, there is preferably no change in the position of the device carrier relative to the mounting rail.

In one embodiment, the device carrier for producing the operating position can only be attached to the mounting rail by means of the detent spring. The device carrier can preferably be held in a position which the components of the system occupy before the operating position is reached, and in which only the device carrier, but not yet the cover, is fixed to the mounting rail via the catch spring on the mounting rail. The retaining web preferably does not contribute to fastening the device carrier to the mounting rail. In particular, the holding web only rests on the mounting rail in the operating position when the cover is held on the equipment carrier by the fixing section. In the operating position, the holding force by which the holding web is held on the mounting rail is preferably small compared to the holding force with which the detent spring is held on the mounting rail. The attachment of the device carrier to the mounting rail is preferably already possible in that the device carrier is moved in the vertical direction relative to the mounting rail. The device carrier can preferably be fastened to the mounting rail in such a way that the movement takes place in the vertical direction, as a result of which the retaining web is inserted into the receptacle of the side wall of the mounting rail and as a result of which the detent spring is applied and held on the side facing away from the groove transversely. After the end of the movement in the vertical direction for fastening the device carrier to the mounting rail, the locking spring preferably engages behind a section of the mounting rail, in particular the section of the second groove wall for producing a positive connection between the locking spring and mounting rail.

In a preferred embodiment, the holding web has an abutment section at the end of its vertical extent. The contact section is designed such that it runs in the transverse direction. The plant section lies in the operating position with a first contact point on the mounting of the mounting rail. The retaining web also bears against the fixing section of the cover with a second contact point. The first and the second contact point are preferably at a small distance, in particular between 1 mm and 15 mm, in order to produce the smallest possible, in particular no, deflection of the holding web between the first contact point and the second contact point when the holding web with the Bearing section bears on the mounting rail and the fixing section of the cover bears on the retaining web. The deflection is to be understood as a relative movement of the contact points caused by a deformation of the holding web. The contact points are preferably arranged at a short distance from one another. The contact points are preferably spaced apart from one another in the vertical direction by less than 7 mm, in particular less than 5 mm, in particular less than 3 mm. The contact points are preferably less far apart in the vertical direction than in the transverse direction. Various design options are known to the person skilled in the art, with the aid of which low-deformation designs of the holding web can be realized. In particular, an advantageous embodiment of the contact section can take place such that it runs predominantly in the transverse direction between a transverse distance from the first contact point and the second contact point. The contact section is subjected to a pressure load in the transverse direction, whereby the deformation of the contact section can be kept low according to the embodiment. In particular, the contact section has a larger transverse extension than a vertical extension. The plant section particularly preferably has a transverse extension which is at least twice as large as the vertical extension. In other versions, the System section of the device carrier, that is, when viewing the device carrier independently of the other components of the system and without external force acting on the device carrier, also have a transverse extension that exceeds the transverse distance of the contact points in the operating position. By jointly loosening the device carrier and cover, the assembly and disassembly of the system, for example for maintenance purposes, can be significantly simplified since the cover and device carrier can be removed from the mounting rail in one step and access to the receiving space can be given directly. In general, the arrangement of the fixing section between the first groove wall and the second groove wall in the groove, the fixing section resting in particular on the retaining web and the receptacle of the mounting rail, can be used to seal off the ingress of dirt or moisture. In particular, versions in which the device carrier is designed as a dummy module are sealed in such a way that relevant standards, in particular IP 54, in particular IP 64, in particular IP 65, are met.

The invention further relates to a system which represents a second solution to the problem described above. This system can also have the above-described features of the first solution to the stated problem. Likewise, the system according to the first solution explained above can have the features of the second solution explained below. The system according to the second solution has a plurality of support rails, in particular elongated in the longitudinal direction, and a plurality of covers, in particular elongated in the longitudinal direction. In addition, the system according to the second solution can have a plurality of device carriers, in particular elongated in the longitudinal direction. Each of the mounting rails has two side walls running along the vertical direction, which pass through a bottom section of the mounting rail running along the transverse direction are connected to one another. The system according to the second solution has several system components, each of which comprises one of the mounting rails and one of the covers. Each system component can further comprise an equipment rack. In an operating position of each system component, the cover of the system component is held in a fixed position on the mounting rail of the system component, and the cover and the mounting rail of the system component together enclose a receiving space. In this case, circumferential encirclement around the longitudinal direction is used, particularly preferably continuous encirclement encircling the longitudinal direction. The cover and mounting rail particularly preferably enclose more than 90%, in particular at least 95% of their longitudinal extension length, in particular dust-tight and watertight, in particular in accordance with the standards specified above, around the receiving space around the longitudinal direction. The system comprises a sealing device for sealing two system components arranged side by side in the longitudinal direction. The sealing device comprises an upper part and a lower part. The upper part has a cross section in the manner of a U-shape with a U-base arranged vertically at the top, two U-legs and an open end arranged vertically at the bottom and can be placed along the vertical direction from above and outside on the bottom section of each mounting rail, that its U-legs with their respective inner sides lie laterally on the outside of the side walls of the mounting rail and that its U-bottom rests with its inside on the outside of the bottom section of the mounting rail. The lower part is designed in the manner of a web and is designed for insertion into the open end of the upper part for connecting the U-legs of the upper part.

The system according to the invention in accordance with the above-described further solution to the problem on which the invention is based enables, in a particularly simple manner, the sealing of two system components arranged side by side in the longitudinal direction at their mutually facing longitudinal ends and thus a sealing of the adjacent system components on their end faces when they adjoin one another. It is therefore a sealing of the joints of two system components arranged side by side in the longitudinal direction. While conventionally in generic systems a joint seal against the ingress of water and dust between two system components is provided, which is inserted between the system components before they are connected to one another, the provision of a two-part sealing device in the system according to the invention allows two system components to be sealed from one another after the mounting rails of the two system components have been connected to each other. The system according to the invention thus makes it possible for a light strip to be realized at a desired installation location, for example suspended from a ceiling, by juxtaposing and mechanically connecting the mounting rails of a plurality of system components, the mounting rails of two adjacent system components then being used via the U-shaped upper part and the like web-like lower part are sealed against each other at their previously connected butt joints, after which the covers are then mounted from below on the mounting rails and preferably also lie sealingly on the sealing device. Correspondingly, the two system components arranged next to one another can be sealed on their respective end faces by the sealing device of the system according to the invention, in that both the mounting rail and the cover of both system components each lie sealingly on the sealing device. Due to the multi-part nature of the sealing device, the U-shaped upper part can be applied from the outside to the two adjacent mounting rails at their joints, after which the web-like part Lower part can be inserted into the open end of the upper part and thereby the U-legs of the upper part can be connected. The purpose of the lower part is therefore to close the open end of the upper part, so that the sealing device can also ensure that the system components are sealed at their mutually pointing longitudinal ends from the underside. The upper part and the lower part are particularly preferably each formed in one piece. Alternatively, at least one of the parts, in particular the upper part, can be formed in two parts, so that it is easier to mount on the outside of the mounting rail. In general, the lower part is preferably formed in one piece. In one embodiment, the lower part also has a cross section in the manner of a U, so that the upper part and the lower part each extend outside on the side walls of the mounting rail in the operating position and the assembly position explained below. However, due to its web-like design, which means that the lower part can close the open end of the upper part like a web, the lower part is in any case designed for insertion into the open end of the upper part by closing the open end and the U-legs of the top connects.

Particularly preferably, two of the system components are arranged next to one another in the longitudinal direction in an assembly position, the upper part abutting the outside of the support rails of both system components and the lower part connecting the U-legs of the upper part. A holding device is particularly preferably provided on each U-leg of the upper part for fixing the upper part in the assembly position relative to the lower part, the lower part preferably having two holding devices spaced apart in the transverse direction, each of the holding devices being designed to correspond to exactly one of the holding devices. The holding devices of the To fix the upper part relative to the lower part, upper parts can also be designed, for example, corresponding to holding devices of the mounting rail, which are provided on the side walls of the mounting rail. The lower part particularly preferably has two holding devices spaced apart in the transverse direction, with a holding device corresponding to exactly one of the holding devices being provided on each side wall of the mounting rails and / or on each U-leg of the upper part for fixing the lower part in the assembly position relative to the upper part. Since the lower part connects the U-legs of the upper part in the assembly position, the sealing device has sufficient stability and can therefore ensure a sufficiently long sealing of two system components. The provision of two holding devices and / or holding devices spaced apart in the transverse direction, in particular by the provision of two holding devices or holding devices, which are located on the two transverse ends of the upper part or lower part, enables a particularly robust fixing of the lower part relative to the upper part . By providing holding devices on the upper part, in particular by providing one holding device each on one U-leg of the upper part, each of which is preferably designed to correspond to one of the holding devices of the lower part, the sealing device can be of particularly robust construction and due to the Fixing the upper part, the lower part closing the open end of the upper part particularly reliably. The lower part can preferably be fixed to the mounting rail by an interference fit. The holding device and holding device are particularly preferably designed to correspond to one another in such a way that the lower part is detachably fastened to the upper part by the interaction of holding devices and holding devices. Are particularly preferred Holding devices and holding devices are designed to correspond to one another in such a way that they can be brought into engagement by a vertical and / or transverse movement of the U-legs relative to the lower part. Holding devices and holding devices are particularly preferably designed to correspond to one another in such a way that both holding devices with their associated holding devices can be brought into engagement via a relative movement of the U-legs relative to the lower part, which runs exclusively perpendicular to the longitudinal direction, in particular to a predominant extent in the transverse direction.

In one embodiment, the upper part and the lower part each lie in a sealing manner on the mounting rails of the two system components in the assembly position. In the assembly position, the upper part and lower part are generally particularly preferably in contact with the two system components arranged next to one another in such a way that a sealing line running along the upper part and lower part and closed around the longitudinal axis is formed, which prevents dust and / or water from penetrating, in particular in accordance with IP 54, in particular in accordance with IP 64, in particular in accordance with IP 65, in the receiving space formed by the mounting rails and their covers at the transition between the two system components is prevented. The upper part is particularly preferably in sealing contact with an outer side of the mounting rails, and the lower part is particularly preferably in sealing contact with an inner side of the mounting rails. The outside and inside of the mounting rails refer to the U-shaped cross section. The inside denotes the side of a U-leg that faces the opposite U-leg and the side of the bottom section that faces the U-leg. A particularly simple and effective seal can be achieved by the upper part resting against the mounting rails. By the bottom part with at least one Section rests sealingly on an inside of the mounting rails, the lower part together with the upper part can reliably implement a sealing sealing line around the longitudinal axis.

In one embodiment, the upper part and / or the lower part are each made of two different materials. The upper part is thus made of two different materials, and the lower part is made of two different materials. The upper part and lower part are particularly preferably made from the same two different materials. In one embodiment, a first part section of the upper part or lower part, in particular of the upper part and lower part, which lies against the two system components in the assembly position, is made of a softer material than the second part section of the upper part or lower part, in particular as, if both are made of different materials a second part section of the upper part and a second part section of the lower part, which is spaced apart from the system components in the assembly position by the first part section. The upper part and / or lower part are particularly preferably each produced in one piece. For example, the one-piece production of a component made of two different materials, ie of the upper part and / or lower part, can be realized by a two-component injection molding process or by overmolding a first material with a second material. By realizing the upper part and / or lower part from two different materials in each case, sufficient hardness of the respective part can be guaranteed, on the one hand, and a sufficiently sealing contact surface of the respective part on the system components. For example, the parts can have a hard core, to which soft material is applied on an outside. By making the softer Material, which can be more suitable for sealing than hard material, is in contact with the system components and yet a section with hard material is provided, the double effect of stability and the best possible sealing can be realized as well as possible.

In one embodiment, the lower part lies in the assembly position in a vertically lower end section of the mounting rail on the inside of the side walls of the mounting rail. The side walls particularly preferably each have an undercut which the lower part engages behind. As a result, the lower part can be fixed particularly reliably with respect to the side walls of the mounting rails and ensure a seal with respect to the side walls from the inside.

In one embodiment, the lower part rests in the assembly position on the covers of the two system components in a sealing system, the covers being movable along the longitudinal direction relative to the mounting rails of the two system components while maintaining the sealing system. In general, the cover of each system component is particularly preferably sealed along its longitudinal extent continuously with respect to the mounting rail of the respective system component. By the covers of both system components in the assembly position in sealing contact with the lower part and the covers being movable relative to the support rails of the two system components while maintaining the sealing contact along the longitudinal direction, it can be ensured that in the event of temperature fluctuations in which the covers are located expand in a different way than the mounting rails, tensions within the system components are avoided and at the same time the seal is reliably maintained. The lower part is particularly preferred in the Mounting position fixed in position relative to the mounting rails of both system components, wherein at least the cover of one of the system components, in particular the covers of both system components, is movable in the longitudinal direction relative to the lower part while maintaining the system on the lower part. The cover can be moved against the lower part in various ways, for example via a sealing lip provided on the cover or on the lower part. For example, the lower part can have a sealing lip that presses against the cover of the two system components with a contact pressure. Alternatively, the covers can each have a sealing lip that press against the lower part.

In one embodiment, the cover of each system component has at least one cover end piece and one cover main piece, the cover main piece forming at least 80%, in particular at least 90%, in particular at least 95% of the longitudinal extent of the cover, and wherein in the operating position the cover end piece forms a longitudinal end of the cover . In the assembly position, the cover end piece preferably lies sealingly on the cover main piece and on the lower part, a closed sealing line running around the longitudinal axis running along the mounting rail, along the cover end piece, along the upper part and along the lower part. The design of the cover as comprising at least one, in particular two, cover end pieces and a cover main piece enables the cover to be produced particularly cost-effectively in a manner in which the cover can be easily sealed off from the mounting rail and from the sealing device. For example, the cover main piece can be produced by extrusion processes, whereas the cover end piece is produced by injection molding and is inserted, in particular sealed, in the front end into the cover main piece. Particularly preferred exist in the mounting position two longitudinally spaced closed peripheral sealing lines, of which a first runs along the cover end of the first of the two adjacent system components and a second along the cover end of the second of the system components. As a result, mobility of the covers comprising the cover end pieces relative to the sealing device while maintaining the sealing system can be favored in particular. Particularly preferably, the cover of at least one system component, in particular of both system components, has two cover end pieces, each of which is arranged on a longitudinal end of the cover main piece as explained.

In general, at least the upper part and / or the cover, particularly preferably the upper part and cover, in one embodiment the upper part, lower part and cover each have a sealing lip, a sealing line running around the longitudinal direction running along the sealing lips. Particularly preferably, the covers each have a sealing lip with which they can slide sealingly against the lower part, starting from the mounting position, in the longitudinal direction when the covers of the system components move relative to the mounting rails and thus relative to the lower part fastened to the mounting rails. In general, in the assembly position, the lower part is preferably pressed flat against the mounting rails, while at least the covers rest sealingly on the lower part in the sliding system via a sealing lip.

In one embodiment, a holding device is formed at each transverse end of the lower part and a holding device assigned to one of the holding devices is arranged on each U-leg, in particular A pair of holding devices and the associated holding device are designed to correspond to each other in such a way that the holding device and the associated holding device are moved by one another, in particular a movement of the holding device along the transverse direction from the outside to the transverse center of the mounting rail, while the holding device is fixed to the mounting rail is connected, can be locked together to reach the assembly position. In one embodiment, the holding device and holding device are designed to correspond to one another in such a way that they can be brought into engagement with one another solely by a relative movement in order to fix the upper part to the lower part. In one embodiment, a screw connection is provided which is formed by the holding device and holding device. In the case of a design of the lower part and / or upper part from two different materials, one of which is harder than the other, holding devices and holding devices are particularly preferably formed from the harder material in each case. The locking can take place, for example, via a toothed locking or via a projection locking. For example, the holding device and the holding device can also be designed as a tongue and groove combination, which can be brought into engagement with one another by the movement along the transverse direction.

The U-legs are particularly preferably connected to one another by the U-base in such a way that, starting from a rest position, they can be deflected elastically along the transverse direction in order to mount the upper part on the outside of the mounting rail. According to this embodiment, the upper part is thus designed as an elastic component. When the U-legs are deflected from their rest position, in which the U-legs are further apart from each other in the transverse direction than in the rest position, the U-legs form through their Connection via the U-floor thus a force along the transverse direction to each other, via which they return to their rest position without external force influence. The upper part is particularly preferably designed such that, starting from a rest position in which the U-legs are at a certain distance in the transverse direction from one another at the open end of the upper part, the U-legs can be deflected elastically from the rest position to such an extent that their deflection distance 150 % of the distance is at rest.

Run in the described embodiment both side walls 11 each proceeding from the bottom section 10 along the vertical direction Z, the two side walls 11 each having an identical profile and each forming a receptacle 100 at their vertical ends, with an associated holding web 21 of an equipment carrier 2 and each in each of the receptacles 100 an associated fixing section 31, 32 of a cover 3 is arranged. The side walls 11 each extend from the bottom section 10 to the open end of the mounting rail 1, which lies opposite the bottom section 10 in the vertical direction Z, forming an essentially U-shaped cross section of the mounting rail 1 perpendicular to the longitudinal direction X, as can be seen in particular from FIGS Figures 1 and 2 can be seen. The side walls 11 extend from the bottom section 10 along the vertical direction Z to the vertical end of the mounting rail 1 opposite the bottom section 10, not ending at this vertical end of the mounting rail 1 but starting from the vertical end again in the vertical direction Z towards the bottom section 10 run with the formation of a connector guide and with the simultaneous formation of a receiving wall or groove wall 102, after which the side walls 11 each again run along the vertical direction Z away from the bottom section 10 in the direction of the vertical end opposite the bottom section 10, forming a further receiving wall 102. The side walls 11 are thus profiled in an end section vertically facing away from the base section 10 such that each side wall 11 has three S in this vertical end section running along each other in the vertical direction Z and spaced apart in the transverse direction Y. forms side wall sections, two of which form a connector guide and two form a receptacle 100, so that the middle of the three side wall sections simultaneously contributes to the formation of the connector guide and the formation of the receptacle, one of which Design of the side walls 11 is generally advantageous for the system according to the invention.

While in Figure 1 For purposes of illustration, the connector 5 included in the illustrated embodiment is not shown, such a connector 5 is shown in FIG Figure 2 shown, the system being in the operating position and the connector 5 being arranged in the connector guides formed by the side walls 11. Two support rails 1 adjacent to one another in the longitudinal direction X are mechanically connected to one another via the connector 5, in that the connector 5 is inserted into the respective connector guides of the support rails 1, which are formed by the side walls 11 of the two support rails 1, the two support rails 1 being of identical design could be. In Figure 3 is shown for explanatory purposes of the connector 5 in its operating position relative to a mounting rail 1 of the system, ie it is inserted into the connector guide of the mounting rail 1 at the end. A second mounting rail 1 can be fixed to the first mounting rail 1 by pushing it onto the connector 5 along the longitudinal direction X and thereby inserting the connector 5 into the connector guide of the mounting rail 1. In Figure 3 an electrical plug connection 6 is also shown for illustrative purposes, which is provided on the connector 5 in a preferred embodiment and which is designed to correspond to a further electrical plug connection which is connected to the further, in Figure 3 not shown, with the in Figure 3 shown mounting rail 1 is provided for connecting mounting rail 1.

From the synopsis of Figures 1 to 3 is the special design of the receptacles 100 formed by the side walls 11 and the fixation of the device carrier 2 and Cover 3 can be seen in these recordings 100. The equipment carrier 2 has two holding webs 21 which are inserted into the receptacle 100. By inserting the holding webs 21 into the receptacles 100, a groove with a first groove wall 101 and a second groove wall 102 is formed with reference to each combination of the holding web 21 and the corresponding side wall 11. A fixing section of a cover 3 is arranged in this groove, which has two fixing arms 31, 32 in the exemplary embodiment described. In the operating position shown, the first fixing arm 31 presses along the transverse direction Y against the first groove wall 101, which is formed by the holding web 21 of the device carrier 2. The second fixing arm presses along the transverse direction Y, but in the opposite direction with respect to the pressing force exerted by the first fixing arm on the first groove wall 101, against the second groove wall 102, which is formed by the side wall 11. The two fixing arms 31, 32 are spaced transversely apart from one another over a vertical section of the groove and can be deflected relative to one another from a rest position in the transverse direction Y to form a restoring force acting in the transverse direction Y. In the operating position shown, the fixing arms 31, 32 are deflected from their rest position, as a result of which they exert a corresponding contact force along the transverse direction Y against the first groove wall 101 and the second groove wall 102. In the exemplary embodiment described, the arrangement of the connector 5 in the connector guide particularly preferably contributes to the stability of the fixing of the cover 3 and the device carrier 2 in the receptacle 100. This is because the connector 5 provides a support for the second groove wall 102 formed by the side wall 11, so that the second groove wall 102 is stabilized with regard to the pressing force exerted on it by the second fixing arm 32.

In the described embodiment, the of Sidewall 11 formed second groove wall 102 a step on which a projection provided on the second fixing arm 32 abuts vertically in the operating position. In this way, the cover 3 and thus also the device carrier 2 is held particularly reliably relative to the mounting rail 1. In a particularly preferred embodiment, the retaining web 21 also has a step for a projection provided on the first fixing arm 31, as a result of which the fixing of the cover 3 and the device carrier 2 relative to the mounting rail 1 can be further improved. In the exemplary embodiment described, the holding web 21 also lies in the operating position on a section 111 of the receptacle 100 formed by the side wall 11, which lies on the other transverse side of the holding web 21 than the second groove wall 102. This section 111 thus lies together with a section of the second groove wall 102 and a transverse end forming section of the side wall 11 in a vertical end section of the side wall 11, these three sections of the side wall 11 in the vertical end section running along the vertical direction Z and lying next to each other with respect to the transverse direction Y. The section 111 of the side wall 11 thus forms a counterpart for the holding web 21 of the device carrier 2, against which the device carrier 21 presses along the transverse direction Y, while the first fixing arm 31 presses in the same direction along the transverse direction Y against the holding web 21. The holding web 21 is thus held in the transverse direction Y between the mentioned section 111 of the side wall 11 and the first fixing arm 31. Particularly preferably, said vertical section 111 of the side wall 11 and the holding web 21 form corresponding fixing devices, for example step and projection, by means of which the holding web 21 can be held particularly securely relative to the mounting rail 1, as a result of which the cover 3 and the device carrier 2 can be fixed particularly reliably can be guaranteed relative to the mounting rail 1.

In the described embodiment, a circuit board 4 with LEDs is also arranged on the side of the device carrier 2, which points away from the base section 10 and points to a section 111 of the cover 3, which is opposite the base section 10 in the vertical direction Z, which is a system according to the invention is generally advantageous. The person skilled in the art can see that in the described exemplary embodiment of the system according to the invention, a particularly simple assembly of the device carrier 2 and cover 3 on the mounting rail 1 is made possible, in particular by pressing the fixing arms 31, 32 of the fixing section of the cover 3 against the side wall 11 of FIG Carrier rail 1 and against the retaining web 21 of the equipment carrier 2, a seal between the equipment carrier 2, cover 3 and mounting rail 1 is realized. The circuit board 4 with the LEDs arranged thereon is thus located in a receiving space which is sealed from the external environment by the interaction of the holding web 21, the fixing section and the side wall 11. This is a seal of the receiving space designed for the board at its transversal ends, which of course are elongated in the longitudinal direction X due to the elongated design of the mounting rail 1, equipment carrier 2 and cover 3.

In the Figures 4 to 8 Another embodiment of a system according to the invention is shown schematically in different views. In the Figures 4a and 4b the sealing device of this embodiment of a system according to the invention is shown schematically in views, which in the described embodiment consists of two separate elements, namely the upper part 8 and the lower part 7. In the described embodiment, upper part 8 and lower part 7 are thus produced separately from one another and can be connected to one another after their production, which is generally a system according to the invention can be advantageous. In further exemplary embodiments, which are not shown, the sealing device can also comprise, for example, an upper part 8 and a lower part 7, which are integrally connected to one another, for example in an articulated manner, for example via a film hinge, the sealing device being designed in such a way that the upper part 8 has a cross section has in the manner of a U-shape and the lower part 7 is designed for insertion into the open end of the U-shape for connecting the U-legs.

In the embodiment described, the upper part 8 has a U-base 81 and two U-legs 82, a holding device 83 being provided on a lower end section of each of the two U-legs 82, each of which is designed to correspond to a holding device 73 , which is provided at a transverse end of the lower part 7. The terms “above” and “below” refer to directional information with reference to the vertical direction Z, the U-base 81 forming the upper end of the upper part 8 in the exemplary embodiment described and the U-leg 82 starting from the U-base 81 extend vertically downwards. The lower part 7 is designed in the manner of a web which extends elongated along the transverse direction Y. This web-like lower part 7 is designed to be inserted into the open end of the upper part 8 and thus in the transverse direction Y between the U-legs 82. Here, the holding devices 73, which are provided on the transverse ends of the lower part 7, and the holding devices 83, which are provided on the respective inner side of the two U-legs 82, are designed to correspond to one another in such a way that the lower part 7 optionally along the vertical direction Z in the open end of the upper part 8 can be inserted with a positive connection between holding devices 83 and holding devices 73 for fixing the lower part 7 relative to the upper part 8 or that a positive connection between holding devices 83 and holding devices 73 can be achieved in that the lower part 7 is inserted into the open end, while the U-legs 82 proceed from their in Figure 4b shown rest position are bent and thus deflected along the transverse direction Y and then, after inserting the lower part 7 into the open end, the U-legs 82 are brought back into their rest position, during which movement the U-legs 82 proceed from the deflected position into the In the rest position, the holding devices 83 are brought into engagement with the holding devices 73 to form a positive connection between the holding devices 73 and the holding devices 83. The corresponding corresponding configuration of the lower part 7 and the upper part 8 is generally advantageous. In particular, it is generally advantageous to design holding devices 73 and holding devices 83 so that they correspond to one another in such a way that when the holding device 83 moves relative to the holding device 73 along the transverse direction Y, these can be brought into engagement with little effort, but with an attempted relative movement from the holding device 83 to the holding device 73 along the transverse direction Y in the opposite direction, the holding device 83 can be released from the holding device 73 only with a considerably greater effort, in particular with at least twice, in particular at least five times, in particular at least ten times the effort required to hold device 83 and holding device 73 to be brought into engagement with one another by a relative movement along the transverse direction Y. the lower part 7 also has a cross section perpendicular to the transverse direction Y in the manner of a T. Correspondingly, the lower part 7 has a longitudinal central section 72, which extends vertically away from a vertical base section 71. Here The vertical base section 71 extends in the longitudinal direction X on both sides beyond the longitudinal central section 72, in the present case over the same longitudinal extent along the longitudinal direction X. The configuration of the lower part 7 is also in particular Figure 8 evident. It can also be seen from this that, in the present embodiment, the longitudinal central section 72 extends vertically downwards starting from the base section 71 in the assembly position of the system according to the invention. The mounting position is shown below with reference to the Figures 5 to 8 explained in more detail.

Out Figure 4 comprehensively the Figures 4a and 4b it can also be seen that the upper part 8 has a sealing lip 800. This sealing lip 800 is designed for sealing contact with the mounting rail 1 of the described embodiment of the system according to the invention, as is shown below with reference to FIG Figures 5 to 8 is explained in more detail. This sealing lip 800 is formed from a plastic. Both the lower part 7 and the upper part 8 are each made from two different materials, in the present case from two different plastics. A first part section 801, 701 of the upper part 8 or lower part 7 is made of a harder plastic than a second part section 802 or 702 of the respective part. The sealing lip 800 is each formed from the softer material. In general, the design of the upper part 8 and lower part 7, by means of the realization of two different part sections 701, 702, 801, 802, which are made of different material, enables the parts 7, 8 each to have sufficient stability thanks to the second part section 702, 802 and thanks to the first part section 701, 801, the parts 7, 8 can be sealed particularly well with respect to the mounting rail 1 or cover 3. For example, upper part 8 and lower part 7 can be used Two-component injection molding process or by overmolding the second part section 702, 802 with the first part section 701, 801.

In the Figures 5 to 8 are elements of the described embodiment of the system according to the invention, which the sealing device according to Figure 4 has, shown in schematic views in the mounting position of the system. For explanatory purposes, the Figures 5 to 8 different selections of elements are shown, so that their interaction in the assembly position can be seen more clearly. At this point, it should be pointed out that, of course, in a combination of the various solutions to the problem on which the present invention is based, the elements can be in their assembly position and in their operating position with respect to one another, and a luminaire according to the invention can be implemented in the process.

In Figure 5 is a view of two mounting rails 1, a connector 5 and a lower part 7 of the described embodiment of the system according to the invention in their mounting position to each other. The mounting rails 1 are each part of a system component, the two system components comprising further components, in the present case at least also a cover 3 assigned to the respective system component. The mounting rails 1 are arranged next to one another in the longitudinal direction X and mechanically connected to one another via the connector 5, as also above with reference to the first solution of the object on which the invention is based is explained using exemplary embodiments. The lower part 7 is inserted into these mounting rails 1. The lower part 7 runs both with its longitudinal central section 72 and with its vertical base section 71 inside the mounting rails 1 and lies on the inside of the two mounting rails 1 Side walls 11 of the mounting rails 1 each have an undercut, which in a combination of the two solutions described can be formed, for example, by a side wall section forming the receptacle 100, the lower part 7 engaging behind this undercut. This ensures a particularly good fixation of the lower part 7 relative to the mounting rails 1 and also a compression of the lower part 7 on the inside of the mounting rails 1. In Figure 6 is based on Figure 5 the cover 3 of one of the two system components is also shown in the assembly position. In Figure 7 the cover 3 of the other system component and the upper part 8, in each case in the assembly position, are also shown. In Figure 8 is a schematic view of a cross section of the arrangement according to Figure 7 shown.

From the synopsis of Figures 6 to 8 it can be seen that in the assembly position, the cover 3 lies sealingly against the vertical base section 71 of the lower part 7 with a sealing lip 300. Thanks to the design of the lower part 7 with a T-shaped cross section perpendicular to the transverse direction Y, as is evident in particular from FIGS Figures 6 and 8th it can be seen that the cover 3 is sealed relative to the lower part 7 even if the respective cover 3 starts from the in Figure 8 Assembly position shown moved along the longitudinal direction X relative to the lower part 7. Thus, even in the case given in the present exemplary embodiment, the lower part 7 is fixed in position on the mounting rails 1 and the mounting rails 1 are made of a different material than the covers 3 and the covers 3 have a different thermal expansion behavior than the mounting rails 1, ensures that in the case of a relative movement of covers 3 relative to the mounting rails 1 due to the different thermal expansion behavior, the covers 3 during the relative movement along the Continuously seal the longitudinal direction X against the lower part 7. In the present exemplary embodiment, the covers 3 are each formed by a main cover piece 301 and by two cover end pieces 302, the cover end pieces 302 being inserted on the end face into the cover main pieces 301 and terminating at their longitudinal ends. In the present exemplary embodiment, the main cover pieces 301 are each made of plastic by means of an extrusion process, whereas the cover end pieces 302 are produced by means of an injection molding process and are made, at least in part, from a soft material which bears against the sealing device and, in the present exemplary embodiment, forms the sealing lip 300 . The covers 3 can thus be produced particularly inexpensively, with the provision of the cover end pieces 302 making it possible to seal two adjacent system components from one another particularly effectively by means of the sealing device comprising the upper part 8 and lower part 7.

In Figure 9 a view of elements of a further embodiment according to the invention is shown schematically. In Figure 9 is shown the retaining spring 9 of an embodiment of a system according to the invention, which is fixed in position on the device carrier 2 by jamming. In embodiments according to the invention with a holding spring 9, the holding spring 9 is generally preferably fixed in position on the device carrier 2. Out Figure 9 it can be seen that the retaining spring 9 has two spring arms 91 which are designed to engage behind a profile formed by the side walls 11 of the mounting rail 1 in the operating position in order to fix the device carrier 2 to the mounting rail 1. Furthermore is off Figure 9 It can be seen that the equipment carrier 2 has two side walls, an opening 201 being provided in each of the side walls the one in Figure 9 Actuating element, not shown, can be inserted from the outside and can be inserted into a receptacle 92 of one of the spring arms 91 and can thus be locked. Correspondingly, the device carrier 2 can be detached from the mounting rail 1 if, starting from the operating position, the cover 3 is first detached from the mounting rail 1, as a result of which the opening 201 is opened, and then an actuating element from the outside through the opening 201 into the receptacle 92 is introduced. The actuating element in the receptacle 92 is particularly preferably reversibly latchable, ie insertable and latchable and then releasable and executable again. Accordingly, the device carrier 2 can be mounted on the mounting rail 1 by means of actuating elements, after which the actuating elements are subsequently removed and only then is the cover 3 fastened to the mounting rail 1 and device carrier 2 in order to implement the operating position.

In Figure 10 and Figure 11 Another embodiment of the system according to the invention is shown in the operating position and in the maintenance position. Unlike the Figures 1 and 2 is in the Figures 10 and 11 the device carrier 2 is designed in such a way that a detent spring 22 is formed on each side between the respective holding web 21 and the transverse center. With respect to the Figures 10 and 11 The transverse direction is to be understood as horizontal and predominantly parallel to the extent of the base section 10 and of the cover 3, the side walls 11 running in sections orthogonal to the transverse direction, which according to the invention can have general validity in various embodiments. The detent spring 22 thus extends predominantly in the vertical direction, being slightly inclined outwards starting from the transverse center. Figure 10 shows the system in the operating position. At her top At the end, the detent spring 22 forms a section which engages behind the mounting rail 1 in the operating position and bears against the mounting rail 1. The detent spring 22 can be deflected relative to its starting position and form a restoring force with which it presses against the mounting rail 1. The holding web 21 is arranged in the receptacle 100 of the side wall 11 of the mounting rail 1. It rests on the first contact point 211 with the contact section 221 on the receptacle 100. It forms the first groove wall 101 of the groove, in which the fixing section is arranged in the operating position. The fixing section presses at the second contact point 212 with the first fixing arm 31 against the first groove wall 101, as a result of which the analog section 221 of the holding web 21 presses against the mounting rail 1 at the first contact point 211. The pressure is already sufficient to seal the luminaire against environmental influences. In the embodiment shown, the device carrier 2 is held in the operating position on the mounting rail 1 by the detent springs 22 and held indirectly on the mounting rail 1 via the cover 3. Through their contact with the mounting rail 1 at the first contact point 211, the retaining webs 21 further contribute to the system not experiencing any change in the relative position of the mounting rail 1, equipment rack 2 and cover 3 even when shaken. In Figure 11 the system is shown in the maintenance position. The detent spring 22 is in the maintenance position in the starting position, in which it has no restoring force due to a lack of deflection. The cover 3 bears against the holding web 21 of the device carrier 2 by means of the fixing section. In the maintenance position, device carrier 2 and cover 3 have the same relative position as in the operating position. In this case, the fixing section lies with one of the fixing arms 31 at the second contact point 212 on the holding web 21. The equipment carrier 2 and the cover 3 are spaced apart from the base section 10 in the maintenance position. The distance in vertical Direction is larger in the maintenance position than in the operating position. Device carrier 2 and cover 3 are moved by the release movement along the vertical direction from the operating position ( Figure 10 ) in the maintenance position ( Figure 11 ) transferred. The release movement removes the cover 3 from the mounting rail 1, but not the cover 3 from the device carrier 2, so that the release movement transfers device carrier 2 and cover 3 together into the maintenance position. In Figure 11 there is no transverse or horizontal offset of equipment carrier 2 and cover 3 compared to that in Figure 10 shown operating position. By loosening the device carrier 2 and cover 3 together, the assembly and disassembly of the system, for example for maintenance purposes, is significantly simplified, since cover 3 and device carrier 2 can be removed from the mounting rail 1 in one step and immediate access to the receiving space is provided , for this purpose only a corresponding release force is to be applied to the cover 3.

The person skilled in the art can see that the solutions according to the invention thus described make it possible in a particularly advantageous manner to create a receiving space for a circuit board 4 with LEDs that is sealed off from the outside environment. The invention offers both a particularly efficient solution for realizing a seal along the transverse ends of the two system components as well as a particularly effective sealing of two system components which are arranged next to one another in the longitudinal direction and are connected to one another via the sealing device, the sealing device preferably preferring these system components to one another seals facing longitudinal ends of the two system components. Due to the design of the sealing device, it is possible that in a first method step, the mounting rails 1 of a plurality of system components can be connected to one another and installed, after which the Sealing devices can be arranged in each case at the joints of two mounting rails of two adjacent system components and the covers 3 of the system components can be installed in a third method step. Accordingly, the invention provides a particularly easy-to-assemble system for realizing a lamp which is elongated in the longitudinal direction X and has a receiving space which is sealed off from the outside environment, the receiving space being able to have a plurality of partial receiving spaces, each partial receiving space being assigned to exactly one system component and facing each partial receiving space the outside environment is sealed.
